SLUG SAWING TRAY Application May 22, 1939, Serial No. 275,072

1 Claim.

This invention relates to new and useful improvements in slug sawing means and more particularly to a tray for properly holding slugs such as are cast on a Ludlow line casting machine while they are being cut to the proper length.

The principal object of the present invention is to provide a tray for holding slugs in a multiple arrangement while they are being sawed, thus saving considerable time over the present practice of clamping and cutting one slug at a time and having to change a gauge each time a different measurement is desired.

Another important object of the invention is to provide a slug sawing machine which will offer a high degree of safety to the operator.

Another important object of the invention is to provide a cutting tray in which the slugs are held in upright position so that they can be read at a glance by the attendant.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings Figure 1 represents a top plan view of the tray showing the slug and the band saw.

Figure 2 is a section on the line 22 of Figure 1.

Figure 3 is a fragmentary detailed sectional view on a line 33 of Figure 1.

Figure 4 is a perspective view of the tray.

Figure 5 is a perspective view of one of the slugs.

Figure 6 is a perspective view of the matrix used to produce the projection with Roman type.

Figure 7 is a top view of a matrix to be used with Italic type.

Numeral '5 generally refers to the tray while numerals I and 8 generally refer to the band saw and a slug, respectively.

As shown in Figure 1 the table for the band saw is denoted by numeral 9 and is shown dotted in and on this is the customary carriage (not shown) into slots of which can slip the lugs III-l I} at the opposite ends of the tray 6. This tray 6 has the end walls IIII from which the lugs II] protrude, and the back wall I2 in addition to the bottom wall I3. Partitions I4 extend from the back wall I2 and are raised in parallel relation to each other and to the end walls I I todefine slots or troughs I5 for receiving the tail portion I6 of slugs I8, the tail portion I6 resting upon the wall I3 with a slight clearance between head portion I! and partition I4. The partitions M are sufficiently thick so that the head portion I! overlaps of the slugs on the smaller sizes will not interfere with the adjacent slugs. The slugs with the larger head overlaps are taken care of by skipping one or more partitions. The dotted por- 5 tion in Figure 5, denotes the type portion of the slug.

The slugs are arranged in the tray (as one is shown in Figure 1) with the portions thereof to be cut off protruding beyond the open front of the 10 tray. With the portions of the slug thus remaining in the tray, the carriage carrying the tray can be moved along the table 9 and with the saw I in operation the protruding ends of the slugs will be out off. Thus a volume of the slugs can be 15 cut in one operation without requiring individual measuring of the slugs or individual handling of the slugs while cutting. This is a considerable safety factor when the safety of the workmen is considered. I

The member 20 shown in Figure 6 is used with Roman type and is placed on the right hand side of the usual Ludlow type-setting stick (not shown) and causes a round projection Ifia to be cast on the top of the Ludlow slug, a given dis- 25 tance from the type face. Numeral 2| represents a member intended for use in the same manner as the member 20, but only when Italic type is to be set.

While the foregoing specification sets forth the 30 invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

A slug sawing tray for Ludlow slugs having T-heads comprising a rectangular flat bottom 40 frame having parallel side walls, a rear end wall, and an open front end, and a plurality of partitions extending from end to end of the frame in parallel equidistantly spaced relation to each other and to said side wall to form open top pockets for said slugs open at the front ends of the frame for extension of the slugs therefrom, said partitions and side walls being constructed and arranged for location of the heads of the slugs above said pockets in edge to edge spaced apart relation and in a common horizontal plane.
